My invention relatesto improvements in cooking devices cooking pastry cornets and consists in an improved .construction of machine whereby cornets may be as conveniently and more ex l peditiously baked than in the ordinary hand devices, and to,that end consists in the fea.- tures of construction and combination hereinafter niore particularly described and claimed.

designed particularly for' members illustrating a cooperating trimming knife.

Referring to the drawings A represents the frameworkl of the machineand B an oven supported in the ends of said framework upon a-shaft 2, saidshaft being preferably hollow atone end. The oven B is. made up. of a plurality of segments 3 fitted together as shownin Fig. 3 and secured be-v tween the lend walls of the oven as by means of bolts 4. Each oven segment carries a plurality of outer mold members 5, The inner ends ofthe outer molds 5, within the oven,

arepreferably separated by the solid wall portion 6 forming heat conductin surfaces. Each oven'segment is formed wit exterior outward projecting end studs 7 and central studs 8for the purpose hereinafter set forth. Carried by the end walls of the framework and partially surrounding the oven are the tracks 9, said tracks being each spaced farther from the oven at their rear thanat their front ends. The reareiids of the tracks constitute the entrance ends in the rota-tion of the oven. The cooperating inner mold ineinbers 10 are supported by a plate 11 formed with slotted end openings 12 and central round openings 13 to receive respectively the end pins'? and center pins 8 when said bar is placed upon one of the oven segments with the inner mold members extending into vthe outer mold members. The inner mold members 10 urerotatable and vertically slid able in the plate 11. v Euch inner mold inember carries at its upper end a gear wheel 14, the gear wheels of the dierent molds intermesliing. Upon the underside of each gear wheel is formed a cam 15 coperating with acum 16 on the upper surface of the plate 11. The inner mold members are hol'- lowed angl formed with rectangular openings 1'? in their upper ends into which may be fitted a suitable wrench 18 by which the molds may be turned to loosen them in the cornets'in the process of cooking. In the rotation of the molds the coperating cams 15 and 16 will raise the inner molds, as indicated particularly in Figs. 13 and 14. Carried by the upper end of each inner mold is an outwardly and downwardly extending` trimming blade 19 which in the process of baking extends into the inclined sbt 20 in the edge of the coperatin g outer mold. The rotating of the inner mold will carry the trimming blade 19 out'of the slot 20 and around the upper face of the outer mold, as indicated in Fig. 16, to trim the cornet.

Each plate 11 has central support 21 upon a longitudinally extending spring bar 22,

' said bar carrying rollers 23 'at its ends to tra rel within the tracks 9 in theoperation of the machine. Supplementary coil springs 24 are interposed between the ends of the spring bar and plate 11. For the purpose of lifting the inner molds onto and oil' from the oven I provide the hand :levers having fulcrum support 26 upon links 27, said links in turn' having pivotal support upon the rod 28. The hand levers are formed at their inner ends with notches 29 to receive the angular bearings 30 upon the ends of the plate 11. The oven is revolved by a suitable handle 31, journaled upon one end of the machine and formed with a gear pinion 32 intermeshing with a gear wheel 33 carried by the adjacent end of the oven supporting shaft 2. The oven may be interiorly heated through the medium of a suitable gas conducting pipe 34 extending through the hollow end of the oven shaft intothe interior of theoven and carrying upon its inner end a suitable burner not shown. The inner mold members are heated as by means of the gas burners 35 supported underneath the oven and having burners 36 in position to direct the flame jets into the open ends of the inner members at predetermined points in their travel around the tracks 9. as indicated in Fig. 5. For the purpose of slightly separating the mold members as the outer molds leave the delivery end of the tracks I provide, above the delivery ends of the tracks, guides 37 which will engage with the bearings 30 and slightly carry the inner molds away from the outer molds.

Forthe purpose of handling the dough I provide a;` suitable dough receptacle C havmg slidable upon its bottom 38 a plate 39 formed with a plurality .of openings not shown. y lThe bottom 38 of the dough receptacle extends forwardly to form a shelf 40 which is formed with a plurality of openings 41V corresponding in size tothe openings in the slide 39. The openings in the slide constitute lpockets to be filled with dough, and when the slide is drawn forward to cause its openings to register with fthe openings 41, the dough in said pockets will drop through said openings 41. To receive the dough as it drops through the openings 41 I provide a bar 42 provided with end handles 43A and formed with a plurality of pocket-s 44 'to receive the dough as it drops through the openingsfll. Un*- derneath the shelf 40 l` provide" suitable supporting brackets 4,5 for the bar 42. In

use the bar 42 will be placed upon supports 45 and the slide 39 manipulated to till the pockets 44. The bar may then be removed from the supports and the doug in thepockets 44 po-ured from said pocket` through their mouths 46 into the outer molds 5 in the upper oven segment.

Among the important features of my invention is the spring supporting bar 22 for the inner mold members by means of which the mold members are resiliently held in cooperation with the outer mold members, allowing the inner mold membersto be vforced outward by the gases generated in cooking the-cornets, to allow the escape of such gases. 'Further by means of the guideways 9 which are spaced farther from the .oven at the rear than at the front endsthe mold members are gradually brought closer together in the rotation of the oven. AI1- 85 other important feature of my invention is the central pins 8, the outer ends of the plate 11 being free and longitudinally guided by the pins 7 extending into the slotted openings 12. The center of the late 11 is thus held rigid allowing longitu inal expansion toward each end and avoiding the binding which takes place were the bar rigidly supported or unanchored. By means of the driving connection 14 bet en the in- 95 ner mold and by the cams 15 anvdl the inner mold members are simullnously rotated as well as raised to fr Ve cornets and also bringr the knife 1 position for trimmin The inner mo A embers be-4 100 ing of the c iaracter shown and being liftable onto and away from the oven by the hand levers give the advantages inherent in the ordinary hand molds and afar greater capacity and the particular character of cooperating dough device shown assists in the effective use of the machine.

shown in Fig. 8 the plate 11 is preferably curved upwardlynin the center soas to cause its ends to fit snugly against the oven. ln operation'the center of the plate will be sprung against the oven, by the bars 22, and

the ends of the plate will be held from springing, upwardly by plementary springs 24.
